As I have said before here I believe the issue has to do with pod construction.......the internal filter if it drops to close to the bottom of the pod the lower puncture pin will tear it allowing grounds to plug the bottom pin/outlet. When it gets plugged the coffee has nowhere to go and builds pressure blowing the lids of the pod off. It is by trial and error I have found I have no issue with Kirkland (Costco) pods, Green Mountain pods and most main label pods. I also remove the pod holder from my brewer (Hamilton Beach Flexbrew) and push the new pod into it by hand thus insuring the pod does not get over crushed puncturing the bottom. Rarely do I have a lid blow now. The worst pod I have used that consistently popped was the Smart and Final First Street Brand. Which is unfortunate because they usually have a good price point.
